Guerra, a retiree from Boston, was reaching into a pantry for some tea when she heard a sound like a bomb. She dropped to the floor and picked up a bullet, so hot she had to drop it.

The bullet had punched through a garage door and an air-conditioning closet before it came into the pantry.

"It was like some kind of force pulled me away, please don't think I'm crazy. A second more and I would have got it," Guerra said.

The gunfire came from the direction of Florida's Turnpike, which runs a few hundred feet from the homes on the edge of the Waterways of Delray community, police said. It was not clear, if the shots came from a car on the turnpike or from someone standing behind a hedge that screens the homes from the highway.

Police have made no arrests and are continuing their investigation.

Of the dozen homes on the street, only three were hit, including the only two occupied at the time.

Before Alex and Matilde Alfaro moved into their West Tranquility Lake Drive home, they lived in a crowded condominium neighborhood in western Dade County, Matilde Alfaro, 65, said.

"I never thought there was this kind of crime here," Alex Alfaro, 67, said.

The Alfaros had never been victims of crime until now, he said.

The Alfaros were just sitting down to dinner at about 7:45 p.m. when, "I heard a "PRAAACK! from the front of the house," Matilde Alfaro said.

A bullet had hit the trunk of their car and ricocheted into the back window, shattering it.
